Bookkeepers, clerks and many other people who are required to do a great deal 01' writing very often find it necessary to use fountain I pens or ordinary pens having fine, medium or point.

To obviate the above condition and to facilitate the work of bookkeepers, clerks and othen persons' required to do different grades of writing, this invention has been devised to is provide an improved pen having a plurality of points of either the same or different slzes afior'din'g a pen permitting any selected one of the multiple points thereof to be used independently of the remaining points to permit fine, medium or coarse writing to be produced.

It is an object of this invention to provide ascribing instrument pen having a plurality of points'adapted to be used independently of each Other. i

Itis'also an object of this invention to provide an improved scribing instrument pen comprising'a plurality of points adapted to be connected together at their shank portions to permit all of the points to be mounted as a unit on-a penholder. 7

It is a further object of this invention to provide an improved penhaving a plurality of writing points of either the same or different sizes and adapted to be mounted in a Beholder over a multiple-type feed bar to permitfthe pen points to be independently sup plied with ink.

It is furthermore an object of this invention to provide animproved pen comprising a plus0 rality'of writing points joined by a cylindri-- call shank adapted to be mounted in a penholder to completely close the space around thepen feedbar to obviate leakage of ink out of the feed end of the pen holder.

provide-a multiple-point pen adapted to be constructed of a unitary tubular member formed to provide a supporting shank and having one end of the tube drawn out and 59 formed to provide a plurality of scribing Still-another object of this invention is to points adapted to beused independently of one another and adapted to be supplied with ink from a common feed bar over which the multiple pen point is adapted to be engaged when inserted in the end of a pen holder or barrel to close the space between the holder and the shank of the multiple type pen to obviate leakage of'ink out of the end of the holder. 7

It is an important object of this invention to provide an improved multiple-type pen point and feed barfor use therewith said pen point having atubular shank and aplurality of writing points of either the same or different sizes adapted to be used inde pendently of one another and adapted to be independently fed from the feed bar.

Other and further important Objects will be apparent from the disclosures in'the specification and drawing.

The invention (in a preferred form) is illustrated in the drawing and hereinafter more fully described."

Figure 8 is an enlarged fragmentary elevational view of one of a fountain pen barrel having a modified form of multiple type pen point engaged over a feed bar and inserted by means of a retaining ring within the mouthpiece of the barrel.

As shown on the drawing:

The reference numeral 1 indicates a foun tain pen barrel provided with a nozzle 2 at one end terminating in a mouthpiece or collar 3. The mouthpiece 3 of the fountain pen barrel is adapted to have removably engaged therein an improved multiple type fountain pen embodying the principles of this invention and comprising a cylindrical shank 4t constructed of metal and having one end thereof drawn out to provide a tapered head 5 provided with two oppositely positioned depressions 6. The head 5 has the outer end thereof restricted to provide a tapered end piece, each of the opposite sides of which is provided with a longitudinally disposed slot 7 having an enlargement at 8. The outer end of the slot 7 is reduced in size and continues downwardly to the end of the tip so that each side of the tapered tip is slit to provide two nibs 9. The tapered tip end of the multipletype pen is also cut or slit transversely to provide the slot 10, thereby separating the two sets of pen nibs 9 to provide a substantially fine point writing pen on one side and a heavy or coarse writing point on the opposide side, with both of said pen points adapted to be fed from the interior, as hereinafter more fully described.

Engaged in the nozzle end 2 of the fountain pen barrel is a removable ink feed bar of the multiple-feed type and comprising a shank 11, a reduced body portion 12 of a diameter .sufficient to snugly fit through the cylindrical shank 4 of the multiple type pen point, as

, clearly illustrated in Figure 2. The outer end of the body portion 2 is tapered to fit into the tapered interior of the head portion 5 of the multiple-type pen and project to a point substantially beyond the enlarged hole 8 of the pen point slot 7. The feed bar is pro vided with an axial passage 13 to permit ink to be drawn into the barrel 1 in certain types of fountain pens. It will, of course, be understood that the axial passage 13 may be omitted or may be provided in other portions of the feed bar, depending upon the type of fountain pen in which the feed bar is used. The improved feed bar is provided with two longitudinally positioned exterior pen point ink feed passages 14, which are disposed opposite one another and extend throughout the entire length of the feed bar and afford independent feed passages for ink from the interior of the barrel 1 to the respective pen points formed on the end of the pen head portion 5. By this arrangement, it will be seen that the improved multiple-type pen point is engaged over the outer end of the multiple-type feed bar and both members are inserted into the nozzle end of the fountain pen barrel so that the tubular shank portion a of the improved multiple-type pen is tightly engaged around the reduced body portion '12 of the bar and to the inside of the mouthpiece 3 of the nozzle 2 to completely close the space surrounding the feed bar. This novel arrangement obviates leakage of ink from the fountain pen barrel around the exterior of the shank portion 11 of the feed bar, so that ink from leakage does not accumulate around the outer end of the mouthpiece 3 at the end'of the barrel, which is the cause of so much trouble in the ordinary type of fountain pen where only a single pen point is used and where the shank of the pen point extends only around a portion of the body of the feed bar. A

In order to provide a convenient arrangement whereby the tip end of the two pen points may be slightly separated to facilitate grinding and finishing of the same, the outer portion of each of the depressed surfaces 6 of this multiple-type pen point is provided with an indent 15 which tends to spring the ends of the pen points outwardly away from one another a slight degree.

Figure 5 illustrates a modified form of multiple-type pen point in which a metal tube is shaped to provide a shank portion similar to the portion 4: illustrated in Figure 3 and a head portion corresponding to the head portion 5 of Figure '3 but with said head por tion drawn outwardly and tapered to provide three depressions similar to the depressions 6 illustrated in Figure 1. The tapered end of the modified head portion is then cut to provide three converging slots 16 positioned 120 apart and forming three pen points 17, 18 and 19, each of which is provided with a longitudinally positioned slot 20, to provide a pair of pen nibs to permit ink to be fed to the tips of the pen points. The ink feed slots 20 are similar to the slots 7 illustrated in Figure 1.

It will thus be seen that Figure 5 illustrates the extreme tapered end of a multiple pen point which includes three separate pen points of different sizes, with said pen points having the head portion thereof integrally connected and integrally formed on a tubular shank similar to the arrangement illustrated in Figure 3. If preferred, the three pen points illustrated in Figure 5 may all be of the same size, so that, if any of the points is broken or injured, one of the remaining two points may be used. i i

Figure 6 illustrates an elevational view of a feed bar of the multiple-feed type adapted for use with the three pen point arrangement illustrated in Figure 5. The multiple form of feed bar comprises a shank 21 having integrally formed thereon a body portion 22 of reduced diameter, the outer end of which is tapered to form a feed head 23. The exte rior of the feed bar is provided with three longitudinally positioned ink feed grooves 24 positioned 120 apart and extending from the end of the shank 21 longitudinally through the entire length of the body portion 22 and then along the tapered head 23 to substantially the end thereof. The three-way pen. illustrated in Figure 5 is adapted to be engaged over the feed bar illustrated in Figure 6, similar to the arrangement shown in Figure 2, after which the shank. end of the feed bar is projected into the nozzle of a fountain pen barrel, with the cylindrical shank of the multiple-type pen positioned around the body portion 22 of the feed bar and within the mouthpiece 3. This arrangement prevents ink from the interior of the barrel from leaking out between the inner wall of the nozzle 2 and the exterior wall of the shank portion 21 of the feed bar.

Figure 7 illustrates a modified form of feed bar for a 1nultiple-type pen point. This modified form of feed bar comprises shank 25 having integrally formed thereon a body portion 26 of reduced diameter and a tapered head 27 formed on the outer end of the body portion 26. A single longitudinally disposed feed groove 28 is cut longitudinally in the exterior wall of the shank 25 and the body portion 26 and extends a short distance intothe tapered head 27, where it communicates with circular inkdistributing groove 29. The outer end of the tapered head of the feed bar is provided. with three auxiliary or tributary ink-distributing grooves 30 positioned 120 apart, with the inner ends of said grooves communicating with the ink-distributing circular groove 29. This arrangement permits ink from the interior of a fountain pen barrel to be carried out through the single feed groove 28 into the distributing circular groove 29, from which the ink may be distributed to any one of the auxiliary grooves 30 leading to a particular one of the pen pointsof the multiple-type pen illustrated in Figure 5.

Figure 8 illustrates a modified form of multiple-type pen point adapted to be engaged over a multipletype feed bar 31. in this case, the multiple-type pen point comprises a plurality of separate pen points 32 shaped to fit around the feed bar 31 and having the shank portions thereof clamped around the feed bar by means of a ring or sleeve 33 which is adapted to project into the mouth of the mouthpiece 3 of a fountain p'enunozzle orbarr'el to-hold the various pen points properly associated with the multipletype feed bar which is constructed with a number offfeed grooves corresponding with I the number of pen points, so that each pen point may-be individually fed when in use. M It will, of course, be understoodthat nunierous details of construction may be varied through awide range without departing from the principles of this invention, and itis, therefore, not purposed to limit the invention otherwise than-necessitated by the scope of the appended claims;
